Device and method of handling transmission/reception for serving cell

Abstract

A communication device for handling transmission/reception for a serving cell comprises a storage unit for storing instructions and a processing circuit coupled to the storage unit. The processing circuit is configured to execute the instructions stored in the storage unit. The instructions comprise receiving an indication indicating at least one subband unit of a serving cell from a network; and performing a communication operation in the at least one subband unit with the network, after receiving the indication.

What is claimed is: 
     
       1. A communication device for handling transmission/reception for a serving cell, comprising:
 a storage unit, for storing instructions of: 
 receiving an indication indicating at least one physical resource block (PRB) group of a plurality of PRB groups of a serving cell from a network, wherein at least one location and at least one bandwidth of the at least one PRB group are configured by a higher layer signaling transmitted by the network; and 
 performing a communication operation in the at least one PRB group with the network, after receiving the indication; 
 wherein each of the plurality of PRB groups comprises at least one physical uplink (UL) control channel (PUCCH) resource; 
 wherein each of the at least one PUCCH resource indicates a starting symbol index and a duration of a PUCCH; 
 wherein the communication operation comprises transmitting a UCI and a demodulation reference signal (DMRS) with a PUCCH format in a PUCCH and a physical UL shared channel (PUSCH) in one of the at least one PRB group, the PUCCH and the PUSCH are transmitted according to a time-division multiplexing (TDM) scheme, and the PUCCH is transmitted according a code-division multiplexing (CDM) scheme; and 
 a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit. 
 
     
     
       2. The communication device of  claim 1 , wherein the communication operation comprises a listen before talk (LBT) performed in a first set of the at least one PRB group. 
     
     
       3. The communication device of  claim 2 , wherein the storage unit further stores the instruction of:
 transmitting at least one of data and control information via the first set of the at least one PRB group to the network according a result of the LBT. 
 
     
     
       4. The communication device of  claim 1 , wherein the communication operation comprises a measurement performed in a second set of the at least one PRB group. 
     
     
       5. The communication device of  claim 4 , wherein the storage unit further stores the instructions of:
 performing a LBT in a third set of the at least one PRB group; and 
 transmitting a measurement result of the measurement via the third set of the at least one PRB group according to a result of the LBT. 
 
     
     
       6. The communication device of  claim 5 , wherein the measurement result comprises a LBT successful rate of the third set of the at least one PRB group. 
     
     
       7. The communication device of  claim 1 , wherein the at least one location or the at least one bandwidth of the at least one PRB group is determined according to a bandwidth of the serving cell. 
     
     
       8. The communication device of  claim 1 , wherein each of the at least one PRB group comprises a plurality of consecutive PRBs. 
     
     
       9. The communication device of  claim 1 , wherein a maximum number of the plurality of PRB groups is 4. 
     
     
       10. The communication device of  claim 1 , wherein the plurality of PRB groups are not overlapped, partly overlapped or completely overlapped. 
     
     
       11. The communication device of  claim 1 , wherein the communication operation comprises:
 transmitting the physical UL shared channel (PUSCH) in the at least one PRB group of the serving cell to the network. 
 
     
     
       12. The communication device of  claim 1 , wherein the duration of the PUCCH is a long duration or a short duration.
